Pixel array of fringe field switching liquid crystal display panel and driving method thereof

Abstract

A pixel array of a fringe field switching (FFS) liquid crystal display panel includes a plurality of gate lines, a plurality of data line, a plurality of pixel electrodes, and a plurality of common lines. The gate lines are disposed parallel to each other along a first direction. The data lines are disposed parallel to each other along a second direction. A plurality of sub-pixel regions is defined by the gate lines and the data lines. The common lines are disposed along the first direction and electrically isolated from each other. Each of the common lines includes a plurality of common electrodes extending along the second direction. The two adjacent common electrodes of each common line are respectively disposed in the two adjacent sub-pixel regions which are located in different rows.

Description

BACKGROUND[0001]1. Technical Field[0002]The disclosure relates to a pixel array of a fringe field switching liquid crystal display panel and a driving method thereof, and more particularly, to a pixel array of a fringe field switching liquid crystal display panel with a plurality of common lines and a driving method thereof.[0003]2. Description of Related Art[0004]Liquid crystal display panels are applied in many kinds of consumer electronics such as flat TVs, laptop computers, and cell phones. Fringe field switching (FFS) liquid crystal display panels have been developed for improving narrow viewing angle issues in liquid crystal display panels. The main features of the FFS liquid crystal display panel include that common electrodes and pixel electrodes are disposed in different layers of an array substrate (also called a thin film transistor substrate), and a wide viewing angle effect may be achieved by an electrical field generated by the common electrode and the pixel electrode....

AI Technical Summary

Benefits of technology

[0007]In the pixel array of the fringe field switching liquid crystal display panel, the common lines, which may be driven independently, are employed with the allocation approaches of the common electrodes in the sub-pixel regions for presenting a dot inversion driving effect by a simplified driving method. Costs of the driving ICs may then be reduced, and the power consumption of the fringe field switching liquid crystal display panel may be also improved.

Problems solved by technology

However, in conventional fringe field switching liquid crystal display panels, a plurality of common lines, which connect to the common electrodes, are electrically connected to each other and may not be driven independently.

Therefore, driving methods of the array substrate have to be more complicated for presenting different display driving effects, such as a dot inversion driving effect.

This results in driving up the cost of integrated circuits (ICs) and high power consumption for driving the array substrate, also leads away from goals of energy saving and carbon reduction.
